Treatment of congenital ptosis by modified frontal muscle suspension

Abstract

Objective To observe the effect of modified frontal muscle suspension for congenital ptosis.Methods 59 cases (73 eyes) with severe congenital ptosis were operated with modified frontal muscle suspension,male 35 (44 eyes),female 24(29 eyes); monocular 45 cases,binocular 14 cased; mild ptosis 6 cases (6 eyes),moderate ptosis 18 cases (20 eyes),severe ptosis 35 cases(47 eyes).Results The effect rate was 90.41％ (66 eyes),the improvement rate was 9.59％ (7 eyes).In early postoperative time,lagophthalmos were often observed in the most cases but gradually disappeared after 3 months.During the 6 months to 3 years of follow-up,no relapse or serious complication was observed.Conclusion The frontal muscle holds not only rich blood-support and innervation,but also enough strength to raise the upper eyelid.The modified frontalis muscle suspension technique is a safe and effective method for congenital ptosis.
